[Cost-benefit analysis of the control and cure of enzootic bovine leukosis, described in the example of a selected territory].

Abstract

Severe economic damage had been inflicted upon numerous industrialised dairy farms by enzootic bovine leucosis in a selected region with predominance of stepwise production. Initial contamination at the beginning of control action and sanitation had been as high as 98 percent. The annual damage, in monetary terms, had been 3,205,041. - Marks, according to calculations. Now, after eleven years of control and sanitation, eradication of enzootic bovine leucosis has come into sight. Even during these eleven years, control action yielded a benefit of 19,005,451. - Marks, that is 1,727,768.20 Marks per annum or 69. - Marks per cow and annum. It will be possible in forthcoming years to bring the cost factor down and, consequently, to further increase the benefit.
